I actually noticed a while back that some mugshots are inconsistent: some of them have this weird, jpeg compression to them, making them look not as crisp as they should be (specifically, Gate, Dynamo, and every investigator except Yammark). Either that or my rips are trash.
The mugshots seem to have this very "dither-y" look to them, and a lot of pixels that supposedly look the same aren't.

It's most apparent with Dynamo (if you zoom in a bit, at least). As I said, maybe they're trash rips, but then again, they were accompanied with the actual in-game palettes, so...
I also noticed that some mugshots have somewhat inconsistent backgrounds, although at this point it's pretty nitpick-y

Again: maybe trash rips, and quite a nitpick, but it's something I noticed.
I really like contributing to this thread, it's fun, so if this seemed kind of irrelevant or wrong, then my mistake.
